In Espial for Atari 2600, you play as a space attack pilot navigating dangerously close to a massive spaceship. Your mission is to battle endless waves of enemy spacecraft and launch missiles at the spaceship. Use the joystick to control your ship and press the button to shoot both lasers and missiles at the same time. Missiles hit where the crosshair in front of your ship is positioned when launched.
